I assume there must be a 1/8" difference between the AC and non AC pulley?
I'm pretty sure I used a AC pulley and put one of the pulley supports plates on the back side as a shim. I plan to change out the harmonic balancer so I will find out what I have.
My crank pulley has a wobble so step one is to change out the harmonic balancer. Needs done anyway. That will tell me if the pulley is bent. Most likely is.
